And yeah, I've gotten the web version to work, but its very unwieldy to do so. Not usable at all for streaming music in the car, which is what I want it to do. Same with Pandora's website, unfortunately.

Hopefully the update to Flash 10.1 which is coming to us at some point will include AIR, at which point the pandora desktop app (and a whole host of other AIR apps) will be available.
